Believe it or not my design sense isn't lacking as much as it would appear! It's just that I was trying to do something different with this particular app. The landing page uses the same framework as the actual app but it looks like that wasn't the way to go. I'll probably end up conforming to typical landing pages and repost within a few days. Please keep an eye out as proof that my design sense isn't as terrible as you think haha!
I went to the site before reading what you explained the site does, and left it almost immediately.
It comes across as spammy and complete information overload.
Hire a designer, or get a friend at least, just to make some visuals for it. It'll be well worth the money. It needs serious work.
